Add retries for helm chart installs.

[hedge-sparrow]

Is your feature request related to a problem? Please describe.

It's possible for a helm chart install to be cancelled by an etcd leadership election, in such a scenario the chart is uninstalled and marked as errored, requiring manual intervention to resolve.

Describe the solution you would like

It would be nice if we could add retries to helm chart installs.

Describe alternatives you've considered

No response

Additional context

Retries for chart installation would probably need fairly strict exponential backoffs and limited retry attempts. (maybe even just one)

Hi @hedge-sparrow, this is already fixed upstream and it will be available in the next release in all currently supported k0s versions (1.26 to 1.30).

This was fixed in #4064
